clk: qcom: gcc-sc7280: Update the .pwrsts for usb gdscs
The USB controllers on sc7280 do not retain the state when
the system goes into low power state and the GDSCs are
turned off. This results in the controllers reinitializing and
re-enumerating all the connected devices (resulting in additional
delay while coming out of suspend)
Fix this by updating the .pwrsts for the USB GDSCs so they only
transition to retention state in low power.
Since sc7280 only supports cx (parent of usb gdscs) Retention, there
are no cxcs offsets mentioned in order to support the Retention
state.
